A mechanism-based multi-trap phase field model for hydrogen assisted fracture
M. Isfandbod, E. Martínez-Pañeda
We present a new mechanistic, phase field-based formulation for predicting hydrogen embrittlement. The multi-physics model developed incorporates, for the first time, a Taylor-base…
Mode II fracture of an MMA adhesive layer: theory versus experiment
Sina Askarinejad, Emilio Martínez-Pañeda, I. Ivan Cuesta +1
Thick adhesive layers have potential structural application in ship construction for the joining of a composite superstructure to a steel hull. The purpose of this study is to deve…
Fracture in distortion gradient plasticity
S. Fuentes-Alonso, E. Martínez-Pañeda
In this work, distortion gradient plasticity is used to gain insight into material deformation ahead of a crack tip. This also constitutes the first fracture mechanics analysis of…
A phase field model for elastic-gradient-plastic solids undergoing hydrogen embrittlement
Philip K. Kristensen, Christian F. Niordson, Emilio Martínez-Pañeda
We present a gradient-based theoretical framework for predicting hydrogen assisted fracture in elastic-plastic solids. The novelty of the model lies in the combination of: (i) stre…
Numerical study of interface cracking in composite structures using a novel geometrically nonlinear Linear Elastic Brittle Interface Model: mixed-mode fracture conditions and application to structured interfaces
L. García-Guzmán, J. Reinoso, A. Valverde +2
Interface cracking is one of the most prominent failure modes in fibre reinforced polymer (FRP) composites. Recent trends in high-tech applications of FRP composites exploit the li…
Mode II fracture of an elastic-plastic sandwich layer
E. Martínez-Pañeda, I. I. Cuesta, N. A. Fleck
The shear strength of a pre-cracked sandwich layer is predicted, assuming that the layer is linear elastic or elastic-plastic, with yielding characterized by either J2 plasticity t…
